The Sealskinz Waterproof Trail Hat is the definitive technical hat for venturing off the beaten track. It is soft enough to fold away into your pocket or pack, and has an adjustable brim that can be worn either up or down to provide excellent protection from rain, wind and sun. Sealskinz' hydrophilic membrane technology is waterproof and windproof to protect you in the wettest and windiest conditions. It is also breathable to help keep you cool at the same time.
